Specification forming part of Letters lPatent No'. 43,11 64, dated J miel-l, 11464.

Be irknown nmz I, Enorm Wem, late of Lawrence, but now a resident of`South Natick,in the count-y of-Middlesex and State of fnre of felt or felted fabrics; and I do hereby following specilication and represented in the accompanying drawings, ot' which Figure 1 denotes a. top view, Fig. 2 a side My present invention may be used with parts of that for which Letters Patent of the United States of America, numbered 40,087,

and dated September 22,ot' the yea-r 1863,

is equally useful with any other kind of machinery for eariiy being'conned to a picker and a .perfo-p the machine -covered by such patent. There fore in:thc accompanying drawings 1 have not for forming the bator bats used in the ma-` chine, but simply have represented the presnient having machinery for felting, and par. ticularly te such' as described in the said patent; and it consists in thc combination and arrangement ofan auxiliary endless fclting Iapr-pn with two main {citing-aprons andthcir platen's, the whole being to operate together In the drawings, the felting apparatus, with made 'at once between Ythe upper and lower fclting-platens, is represented as composed ofary and movable platens, l K L M, arranged drawings.

The endless apron G is supported andworked by-two rollers, d e, while the lower apron, H, is similarly supported and worked by two rollers, g h.. The foremost two of these rollers-viz., e land k--fparc for driving or moving as well as for snpportinglhe aprons, .and they are connected yby gears ik, aixed on their respectiveA shafts. Euch of these endless feltimpa irons G II, as well as thc auxiliary apron u hereinafter explained, is to travel at the Mme rato' of speed.

The upper pinten inve machin'eryvi'or vibrating them, such consisting of a shaft, i',

provided with eccentrica o1 bell-cranks to operate four connectingrods, k k k2 k3, which extend from these eceentrics to projections l l ll from the platens. Ascrew or worm, m, on 'tbe shaft engages with a wornrgear, n, fixed` on another shaft, o, which carries a worin, p, to work in a gear, q, fixed on the shaft of thc roller h.- Byl means of the endless screws or worms m'p, the shaft o, and gears n, q, t', and k, thc endless aprons may be putin movement.

With the two endless aprons (i H andthcir platens I havel combined n third or auxiliary endless apron, U, which extends between the two aprons G H and works around the rollers d e of the apron G, and one or more additional rollers, r s, the whole bein g arranged as shown in the drawings;

Rollers t, u, and o are employed for carrying the bats to be felted. There may be one or more ot such rollers for each sheet of felt to be formed bythe machine, the felt being made of either one,two, or more bats.' `The bats from the rollers ,t u are to he run together andv lcd between the lower apron, H, and the' lower partici. ,the auxiliary apron O, the bat from the' roller n being led around the roller nDWAni) RICHMOND,
